Description

Technical Field

[0001] The invention relates to a filler, in particular to a multi-faceted hollow ball filler. Background Art

[0002] Multifaceted hollow ball fillers have the characteristics of large production capacity, small resistance, large operating flexibility, light weight, high strength, large free space, high temperature resistance, corrosion resistance, good surface hydrophilicity, small wind resistance, low power consumption, large specific surface area and adaptable to a variety of solvent treatment devices. Widely used in sewage treatment, CO2 removal equipment, desulfurization, purification towers and contact reaction towers.

[0003] In the prior art, the multi-faceted hollow sphere fillers are filled into the tower in a stacked state, and the panels are easily inserted into the gaps between the panels on adjacent multi-faceted hollow sphere fillers, resulting in defects such as embedding and biting. A large amount of surface contact and line contact are formed between the fillers, which leads to a small gas-liquid contact area in the tower, affecting the heat and mass transfer effects of the tower and causing certain inconveniences in use. At the same time, the panels on the fillers are easily damaged during movement. Summary of the invention

[0004] In view of the above prior art, the technical problem to be solved by the present invention is to make the contact between hollow ball fillers mainly point contact to improve the processing effect of the fillers and avoid the fillers from biting each other. To solve the above technical problem, the present invention provides a multi-faceted hollow ball filler.

[0005] A multi-faceted hollow ball filler includes a central tube and a panel. The central tube is formed by staggered connection of support rings and connecting rods from top to bottom. A central column is arranged at the center of the central tube. The central column and the connecting rod are connected by curved plates. The curved plates of the same layer are evenly distributed around the central column. The upper and lower curved plates are staggered around the central column. A fixed ring is horizontally arranged on the outer wall at the vertical center of the central tube. The fixed ring is divided into an inner ring, a middle ring and an outer ring. The inner ring is fixed to the central tube. The panel is fan-shaped. The panels are vertically arranged above and below the fixed rings, respectively. The straight edges on both sides of the panels are fixed to the outer wall of the central tube and the fixed rings, respectively. A reinforcing ring is fixed to the outer edge of the panel. The reinforcing ring is parallel to the fixed ring. The outer edges of the outer ring and the reinforcing ring both protrude outward from the outer edge of the panel where it contacts the panel. The top edge of the central tube protrudes upward from the outer edge of the panel where it contacts the panel. The bottom edge of the central tube protrudes downward from the outer edge of the panel where it contacts the panel.

[0006] The beneficial effect of the present invention compared with the prior art is that the protruding design structure of the reinforcing ring, outer ring and upper and lower support rings of the center tube in the present invention can not only reinforce the panel, but also make the surface contact and linear contact between adjacent fillers when the fillers are stacked become mainly point contact, avoiding the biting phenomenon between the fillers, improving the gas-liquid contact area and heat transfer effect, and avoiding the wear of the panel.

[0010] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1 —3.

[0011] A multi-faceted hollow ball packing includes a central tube 100 and a panel 200. The central tube 100 is formed by interlaced connection of support rings 101 and connecting rods 102 from top to bottom. A central column 103 is arranged at the center of the central tube 100. The central column 103 and the connecting rod 102 are connected by a curved plate 104. The curved plates 104 of the same layer are evenly distributed around the central column 103. The upper and lower curved plates 104 are arranged alternately around the central column 103. A fixed ring 105 is horizontally arranged on the outer wall at the vertical center of the central tube 100. The fixed ring is divided into an inner ring 1051, a middle ring 1052 and an outer ring 1053. The inner ring 1051 is fixed on the central tube 100. The curved plate 104 arranged in the central tube 100 increases the specific surface area of ​​the packing, thereby increasing the gas-liquid contact area.

[0012] The above-mentioned panel 200 is fan-shaped, and the panel 200 is vertically arranged above and below the fixing ring 105, respectively. The straight edges on both sides of the panel 200 are fixed to the outer wall of the central tube 100 and the fixing ring 105, respectively. A reinforcing ring 201 is fixed to the outer edge of the panel 200, and the reinforcing ring 201 can stabilize the panel 200 and prevent the panel from being damaged. The reinforcing ring 201 is parallel to the fixing ring 105, and the outer edges of the outer ring 1053 and the reinforcing ring 201 both protrude outward from the outer edge of the panel 200 where it contacts the panel 200, the top edge of the central tube 100 protrudes upward from the outer edge of the panel 200 where it contacts the panel 200, and the bottom edge of the central tube 100 protrudes downward from the outer edge of the panel 200 where it contacts the panel 200. This arrangement can ensure that the contact between the stacked adjacent fillers is only between the reinforcing ring 201 and the outer ring 1053 of the fillers.

[0013] The invention can be used for various sewage treatment, CO2 removal equipment, desulfurization, purification towers and contact reaction towers. When in use, it is directly put into the equipment and the fillers are stacked therein. The reinforcing ring 201, the outer ring 1053, and the top or bottom edges of adjacent fillers are in contact with each other, so that point contact between the edges can be formed, the fillers are separated to the greatest extent, the direct contact and mutual biting of the panels are avoided, the damage of the panels is reduced, the flow rate of liquid and gas is increased, and the purification effect is improved.

[0014] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
